Lost among the major storylines of this postseason (violence, suspensions and upsets, predominantly) is the fact several playoff rookies have broke onto the scene in style, performing like grizzled vets.

They include…

Braden Holtby, G, Washington Capitals

Key stats: 4-3, 2.00 GAA, .940 save percentage

After appearing in just seven games this season, the 22-year-old out-dueled Tim Thomas (you know, the reigning playoff MVP and Vezina winner) in a seven game stunner over the Bruins.

In doing so, Holtby joined Montreal’s Ken Dryden (1971) and Calgary’s Mike Vernon (1986) as the only rookie goalies ever to defeat the defending Cup champions in a playoff series.

Adam Henrique, C, New Jersey Devils

Key stats: 2G-1A-3PTS

Averaging over 16 minutes a game, the Calder Trophy nominee was a clutch performer for the Devils in Round 1. Henrique opened and closed the scoring in New Jersey’s series-clinching win over Florida, becoming the second rookie in NHL history to score an OT winner in Game 7.

The other? Montreal’s Claude Lemieux, in 1986.

Chris Kreider, LW, New York Rangers

Key stats: 1G-0A-1PT, 1 GWG

Kreider made history in Game 3, becoming the first player to win an NCAA title and make his NHL debut in the same year — in the playoffs — since Tony Hrkac did it in 1987 with the University of North Dakota and St. Louis Blues.

As New York’s opening-round series versus Ottawa progressed, so too did Kreider’s role. He scored the game-winning goal in Game 6, then received over 18 minutes of ice time in Game 7 — the only New York forwards that played more were Ryan Callahan, Brad Richards and Derek Stepan.

Brayden Schenn/Sean Couturier, C, Philadelphia Flyers

Key stats: (combined) 5G-5A-10PTS.

Schenn, 20, was a point-a-game player in the opening round against Pittsburgh (2G-4A-6PTS in six games.) Couturier scored a hat trick in Game 2, becoming the youngest player (19 years, 128 days) since Toronto Hall of Famer Ted Kennedy accomplished the feat in 1945.

Gabriel Bourque, LW, Nashville Predators

Key stats: 3G-1A-4PTS

The 21-year-old — who only made his NHL debut on Dec. 28 — was huge in the opening round, leading all Predators with three goals and finishing second in scoring (4PTS). Bourque also tied for the club lead and for third in the NHL overall with a +5 rating.

Minnesota Wild goalie Devan Dubnyk has been the most difficult goalies to score against this season. Leave it to a high-level player like Leon Draisaitl to make it look this, well, “easy.”

Draisaitl scored his 13th goal of 2016-17 by capping this pretty give-and-go play with Benoit Pouliot. You can see the frustration from Dubnyk at the end of the tally, as if he was saying “How was I supposed to stop that?” (though probably with more colorful language).

Draisaitl came into Friday with five goals and three assists in his last five games, so he’s been almost unstoppable lately.
